    Quick Index of Common WhatsApp Business API Problems

    Use this page as a starting point when messages fail, onboarding breaks, or account access is restricted.

    Delivery Errors

  1. Error 131026 (Message Undeliverable): Often caused by recipient/device limitations, invalid templates, or policy constraints.
  2. Error 131042 (Business Eligibility Payment Issue): Usually a temporary Meta billing/eligibility hold; avoid repeated retries.
  3. Error 131060 (Companion Device Visibility): Frequently appears in coexistence mode when message origin differs across devices.
  4. Permission and Authentication Errors

  5. Error #3 (Missing API granular permission): Reconnect Facebook and grant full permissions.
  6. Error #200 (No permission to send): Verify WABA ownership and app/product linkage.
  7. Session expired / token validation failed: Reauthorize the integration and refresh credentials.
  8. Account and Compliance Issues

  9. Account checkpoint / Error 459: Triggered by Meta security checks; complete account verification steps.
  10. Account blocked or banned: File an appeal and pause risky messaging behavior.
  11. Template name not found: Usually caused by template mismatch or using free-form messages outside the 24-hour window.
  12. Setup and Onboarding Problems

  13. Number already registered with another provider: Disconnect from existing INBOX partner before migration.
  14. Phone number not eligible: Build account trust and retry onboarding through the official flow.
  15. Cannot remove from Meta portfolio: Resolve Meta Business Suite 2FA constraints first.

  16. Troubleshooting Workflow That Prevents Repeated Failures

    1. Capture the exact error code and timestamp from Envoy logs.

    2. Classify the issue as delivery, permission, compliance, or onboarding.

    3. Verify account state in Meta (billing, business verification, token validity, WABA status).

    4. Run the fix once and avoid repeated retries that may worsen rate limits or trust signals.

    5. Escalate with context (error code, request ID, timeframe, and actions already attempted).
